An ochre jelly can grow to a diameter of about 15 feet and a thickness of about 6 inches, but can compress its body to fit into cracks as small as 1 inch wide. A typical specimen weighs about 5,600 pounds.

Split (Ex): Slashing and piercing weapons and electricity attacks deal no damage to an ochre jelly. Instead the creature splits into two identical jellies, each with half of the original’s current hit points (round down). A jelly with 10 hit points or less cannot be further split and dies if reduced to 0 it points.

Skills: An ochre jelly has a +8 racial bonus on Climb checks and can always choose to take 10 on a Climb check, even if rushed or threatened.
